After having two different events with my SF3 tuner where the tune didn't upload properly, but the tuner said it did, this makes me wonder. Both times, the upload went just like it always has. But when I went down the street, I'd only get about 1/4 mile from the house and soon as I got on it, it would sputter very badly, backfire and then the car died. Luckily, I keep the tuner in my car after every upload just in case. Both times, I had to load the stock tune, then reload the tune I wanted on there. And in the Florida heat and humidity, that SUCKS.
So I wonder if this update will address this issue. Regardless, even without a change log, I'm going to do it. Because if there was something funky going on with the uploading of a tune that was causing damage to people's engines, SCT wouldn't put that out there because it would be an admission of culpability and they could end up paying for a lot of engines.
